Title: Improvements in or relating to manometers for indicating pressures of air or gases
IPC: G01L7/18
Filed: 1919-05-08
Abstract: 149,074. Whitmore, J. May 8, 1919. Pitot-tube apparatus.-A form of Pitot-tube is shown in Fig. 7. Concentric tubes 31, 32 are formed as the horizontal termination of an upright member consisting of parallel conduits 36<1>, 37<1> communicating with connecting-nipples for india-rubber tubes. The outer tube in the horizontal section is tapered at the end and closed by being soldered to the inner tube, which there forms an impact orifice. Apertures 34 in the wall of the outer tube 31 constitute the static orifice. Communication between the two elements of the Pitot-tube and the atmosphere, as sources of pressure, and a differential pressure gauge is made by means of flexible pipes 20, 21, Fig. 1, passing through a four-way valve 22, whereby measurements may be made of the velocity pressure, static pressure, and total pressure in the fluid conduit wherein the Pitot-tube is placed.

Title: Improvements in or relating to coke oven door latch-actuating apparatus
IPC: C10B25/14
Filed: 1942-08-17
Abstract: 557,502. Coke-oven doors. KOPPERS CO. Aug. 17, 1942, No. 11529. Convention date, June 25. [Class 123 (i)] [Also in Group XII] The latch-bar 31 of a coke oven door is operated by turning a handle 62 secured to a cam 61 on the bar by apparatus comprising a hub 42 from which radial arms 43, 44, 45 project, one arm 44 by a projection 46 releasing the cam, and another arm carrying a counterweighted pivoted member 48 which is swung back, as shown in Fig. 4, when the device is advanced towards the door and tightens the cam by pressure on the handle 62 when the device is drawn back from the door. The latch bars are non-integral with the door, and are of the kind described in Specification 556,723 and the door-operating machine is of the type described in Specifications 523,257, [Group XII], and 557,498, [Group XII]. The latch-operating device is actuated solely by movement due to the approach and retraction of the door-operating machine to and from the door. The machine as a whole is mounted on tracks 11 and its carriage 14 is moved to and from the oven face on wheels 15 and supports a mast 16 to which is affixed a lever system 17, 18, 19, by which the carriage is reciprocated as described in Specification 557,498. The door head mechanism 26 is carried by a threaded column 23, and is raised or lowered by rotation of the column by its motor 21. Forked members 32 carried by the door-head mechanism support the latch bars during their latching and unlatching. In operation, as the door head mechanism approaches the door, the forked members 32 loosely engage the latch bars and rollers 35 are resiliently held by springs 38 in contact with their basses 36 on the door face, and the arm 44 of the latch-operating device approaches the handle 62 of the cam 61. On further movement of the door head mechanism the springs 38 are compressed, and the sealing edge 57 pressed against the door frame, the latch-bar operating devices entering openings 64 and the cam being turned and released by its handle 62 out of contact with its bearing plate 63 as in Fig. 3. The door hooks 27, 28 enter their openings 65, and, the latch bar being freed, elevation of the door-head mechanism raises the door hooks into engagement with the door, and lifts the latch bars from their hooks 60, the door being now supported by the door-operating machine. An initial slight raising of the door while it is still pressed by the forked members 32 and springs 38 exerts a scraping by the sealing edge 57 over the door frame 58, and removes incrustations of carbonaceous material, facilitating good contact when the door is replaced. During movement away from the door face, the springs 38 force the door back into tight contact with the door-hooks 27, 28 and rigidly hold the door, and the door is slewed sideways as described in Specification 557,498, [Group XII]. The door is reseated by repeating the operations in the reverse order.

Patent GB-164931-A (GB)
Title: An improved method or process and apparatus for clarifying oil and grease solvents
IPC: C11B1/10
Filed: 1920-04-27
Abstract: Organic solvents, after being used for dry cleaning or for the extraction of oils, greases, or waxes from textile material, seeds, bones, &c. are freed from suspended matter by agitation with aqueous or alcoholic solutions of potassium, sodium, or ammonium hydrate, or aqueous solutions of alkaline carbonates or other salts such as borax, sodium silicate, sodium aluminate, &c. which have an alkaline reaction.  The process is facilitated by the addition of alcohol or formaldehyde solution, or, in the case of petroleum solvents, of castor oil or liquid castor oil, fatty acids or soaps.  The suspended matter and excess reagent separate out from the solvent, and may be used again for purifying further quantities of liquid.  According to the Provisional Specification glycerine, acetone, and saturated solutions of neutral alkali metal salts may be added to facilitate the separation of the dirt.

Abstract: 855,294. Electric flow-meters. COOK, H. July 8, 1959 [April 14, 1958], No. 11809/58. Class 40 (1). A flow-meter of the hot wire anemometer/ Wheatstone bridge type which is not subject to zero drift and sensitivity variation with change of ambient temperature comprises a pair of thermistors T1, T2 (Fig. 2), separately heated and subject to the gas flow connected on opposite sides of the bridge to which current is fed through potentiometers P1, P2. These potentiometers are individually adjusted during temperature cycling with zero gas flow until the indicating instrument MA shows a steady zero. A third thermistor T3 subject to the same conditions as T1 and T2 is placed in series with MA. The variable resistor VR2 is adjusted until the indicating instrument MA shows no sensitivity variation with temperature. The positions of the thermistors T1, T2 with respect to the gas jets may be adjusted to compensate for their different sensitivities. Pressure compensation could be applied by means of an adjustable resistance in series with the indicator and driven by an evacuated capsule.  The embodiment shown in Fig. 1 is intended for use as a vertical speed indicator wherein the two main thermistors T1, T2 are mounted in a sealed chamber 3 directly opposite two nozzles 1, 2. Nozzle 1 is connected with a heatinsulated container 5, the other nozzle 2 being connected with a tubular static head 7.
